Thank you Cascardo for the reply, We tested in couple of systems with 512GB RAM and we are able to use your makedumpfile to dump the vmcore on 4.13.0-32-generic kernel on Bionic. ==console log=== # dpkg -s makedumpfile Package: makedumpfile Status: install ok installed Priority: optional Section: devel Installed-Size: 493 Maintainer: Louis Bouchard <[email protected]> Architecture: ppc64el Version: 1:1.6.3-1ubuntu1 Replaces: kdump-tools (<< 1.3.4-1~) Depends: libc6 (>= 2.17), libdw1 (>= 0.143), libelf1 (>= 0.142), liblzo2-2, zlib1g (>= 1:1.2.0), perl:any Recommends: crash, kexec-tools Description: VMcore extraction tool This program is used to extract a subset of the memory available either via /dev/mem or /proc/vmcore (for crashdumps).
